Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an adjustable composite roller bearing. Background Art

[0002] The composite roller bearing is assembled from two roller bearings, one axial and one radial, which reduces the bearing volume and simplifies the installation structure, thereby reducing the manufacturing cost. The composite roller bearing has a relatively large radial and axial load-bearing capacity, and each accessory is highly replaceable. It is increasingly used in various gantry lifting systems.

[0003] The existing composite roller bearings may often have a certain distance between the bearing and the contact surface due to measurement size errors during use, making it impossible for the bearing to complete subsequent work well. The entire bearing needs to be disassembled and replaced with a new one before it can be used normally, which is rather cumbersome. Therefore, we propose an adjustable composite roller bearing. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. When using the existing composite roller bearing, due to the error in measuring the size, there may be a certain distance between the bearing and the contact surface, so that the bearing cannot complete the subsequent work well. The entire bearing needs to be disassembled and replaced with a new bearing before it can be used normally, which is relatively cumbersome.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable composite roller bearing comprises a main roller, an outer ring is arranged on the inner side wall of the main roller, a mounting seat is arranged on the back side of the outer ring, a threaded hole is penetrated through the back side of the mounting seat, a movable bolt is arranged inside the threaded hole, an adjusting knob is arranged on the back side of the movable bolt, an inner ring is arranged on the inner side wall of the outer ring, and a rotating shaft is arranged on the back side of the inner ring.

[0007] As a preferred solution of the utility model, a plurality of rolling bodies are equidistantly arranged around the main roller and the outer ring, and mounting grooves are opened on the inner side wall of the main roller corresponding to the plurality of rolling bodies, and the plurality of rolling bodies are rotatably connected to the mounting grooves.

[0008] The technical effect of adopting the above further solution is: the main roller can be directly rotatably connected to the outer ring through the rotatable connection between the rolling body and the mounting groove, so that the bearing can be better used.

[0009] As a preferred solution of the utility model, the movable bolt is threadedly connected to the threaded hole, and the adjusting knob is fixedly connected to the movable bolt.

[0010] The technical effect of adopting the above further scheme is: through the threaded connection between the movable bolt and the threaded hole, the staff can directly turn the adjusting knob, and the adjusting knob will drive the movable bolt to rotate inside the threaded hole, thereby pushing the inner ring and the side roller to adjust the distance between them and the contact surface.

[0011] As a preferred solution of the utility model, an anti-slip ring is sleeved on the outer side wall of the adjusting knob, and the anti-slip ring is made of rubber material.

[0012] The technical effect of adopting the above further solution is that the anti-slip ring made of rubber material can make it more convenient for the staff to turn the adjustment knob.

[0013] As a preferred solution of the utility model, one end of the movable bolt away from the adjusting knob extends to the inside of the rotating shaft, and the movable bolt is rotatably connected to the rotating shaft.

[0014] The technical effect of adopting the above further solution is: through the rotational connection between the movable bolt and the rotating shaft, when the staff turns the adjustment knob to drive the movable bolt to move, the inner ring will not be driven to rotate, which is more stable.

[0015] As a preferred solution of the utility model, a side roller is arranged on the front side of the inner ring, and the side roller is rotatably connected to the inner ring.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] In the utility model, when it is necessary to adjust the distance between the composite roller bearing and the contact surface, the staff can turn the adjusting knob. When the adjusting knob is turned, the movable bolt will be driven to rotate together, so that the movable bolt is horizontally displaced toward the rotating shaft while rotating inside the threaded hole. The inner ring and the side roller can be horizontally displaced through the rotating shaft without driving the inner ring to rotate, thereby changing the distance between the bearing and the contact surface.
